Do shops still sabotage cars for profit?

To sum it up, we have established the fact that the car has to be looked over very well in order for the technician to cover his rear so the customer can't say he neglected to find an issue with the car, yet the customer is usually so sceptical that they think you are trying to sell them things they don't need although you are just alerting them of possible issues that may need adressed now or in the future.

The thing that sucks is when you get customers that ignore your stern recommendations of necessary repairs because they are too cheap to fork out a few bucks, then your warning becomes reality for them a couple days or weeks down the road and they come back crying for you to give them the deal of the century.

Man, I can't even begin to tell you how many different scenario's I have had regarding this, but YES, extensive documentation is the key to covering your arse, and also explaining to customers that you don't have a crystal ball to forsee problems down the road is sometimes next to impossible when dealing with idiots who want to drive a highline car yet can barely afford their mortgage payment.
